About the reserve
Ash dieback safety works will be taking place here from January 2020. Diseased ash trees can become very unstable. The Berks, Bucks and Oxon Wildlife Trust is employing specialist contractors to fell diseased trees where they pose a risk to public safety. The work is being timed to minimise the impact on wildlife. Trees have been surveyed and where possible important bird and bat habitat will be retained. To minimise the number of trees we need to remove and to ensure the safety of visitors, some paths will be closed.

High up in the Chilterns Area of Outstanding Natural Beauty, Warburg Nature Reserve is a remote and magnificent place, rich in exciting plants and animals all through the year. The flower-rich grasslands in the valley bottom give way to extensive woodlands rising up the valley sides. It is the richest BBOWT site in the three counties for orchids. From April right through to August orchids can be found in all of the habitats, including fly orchid and bird's-nest orchid. Warburg Nature Reserve even has its own microclimate with exceptionally cold temperatures on winter nights.
The reserve is home to an incredible range of habitats sheltering thousands of species, and each season there is something interesting to experience.
This is my favourite wild place to come for a walk - you can't match it. BBOWT member
In spring, the woodland is awash with spectacular bluebells and wood anemones. In May and June the reserve has a dawn chorus second to none. The wide sunny rides and open glades of chalk grassland are full of summer flowers, including pyramidal orchid and swathes of aromatic wild marjoram and thyme. These are followed by autumn and Chiltern gentians and glorious colours throughout the tree canopy, while down below, an incredible 900 species of fungi grow. In winter, you can enjoy magical frost along the valley bottom.
Oddities and rarities
In July you can see the yellow bird's-nest, a strange leafless plant that grows in some of the darkest parts of the beech wood. Warburg Nature Reserve is also wonderful for rare butterflies. Oaks provide food for purple hairstreak caterpillars, while the silver-washed fritillary lays its eggs in bark crevices above violets on the ground below.
Nature Detectives Trail
It's free, it's fun and it's great for all the family! From the Interpretation Centre families can pick up a special backpack that includes games, trail notes and spotter sheets for wildlife as tiny as beetles and as big as red kites. Children can follow the trail through the woods, the wildlife pond and the grassy glades at their own pace.
Sustainable charcoal is now available to buy at Warburg Nature Reserve.
